Mechanical shear properties assessed by push-out test.

	Shear stiffness (MPa)	Max shear strength (MPa)	Failure energy (kJ/cm2)
G1: Allograft	4.8 ± 4.1	1.7 ± 2.4	612.7 ± 1078
G2: HA/βTCP	8.2 ± 9.5	2.3 ± 1.9	635.9 ± 484.8
G3: HA/βTCP-HyA	6.6 ± 7.3	2.3 ± 1.7	738.0 ± 562.4
G4: HA/βTCP-PDLLA	6.2 ± 6.0	2.0 ± 2.1	742.1 ± 783.9
RM one-way ANOVA (p)	p = 0.86	p = 0.31	p = 0.1

Data are presented as the mean ± standard deviation.

n = 8 for all groups.

ANOVA = analysis of variance; HA/βTCP = hydroxyapatite/beta-tri-calcium phosphate; HyA = hyaluronic acid; PDLLA = poly-d,l-lactic acid; RM = repeated measures.
